LTC1294 - Single Chip 12-Bit Data Acquisition System
Features
- Software Programmable Features:
Unipolar/Bipolar Conversion
Differential/Single Ended Inputs
MSB-First or MSB/LSB Data - Built-In Sample and Hold
- Single Supply 5V or ±5V Operation
- Direct 4-Wire Interface to Most MPU Serial Ports and All MPU Parallel Ports
- 46.5kHz Maximum Throughput Rate
- System Shutdown Output (LTC1296)
Typical Application
Description
The input multiplexer can be configured for either single ended or differential inputs (or combinations thereof). An on-chip sample and hold is included for all single ended input channels. When the LTC1293/4/6 is idle it can be powered down in applications where low power consumption is desired. The LTC1296 includes a System Shutdown Output pin which can be used to power down external circuitry, such as signal conditioning circuitry prior to the input mux.
The serial I/O is designed to communicate without external hardware to most MPU serial ports and all MPU parallel I/O ports allowing up to eight channels of data to be transmitted over as few as three wires.
